Rustic Grade Oak Engineered Flooring

[karaRobert]

I'm about to install rustic grade oak engineered flooring London (https://www.hoffparquet.co.uk/rustic-grade-oak-wood-flooring-london.html) in my London home, and I'm excited about the rustic charm it will add. However, I've also heard some negative reviews about quality issues. Has anyone had a good or bad experience with rustic grade oak flooring?
Any advice would be appreciated!
